Steps to Share Your Screen on Zoom Using an iMac

To share your screen on Zoom from an iMac, ensure you have the Zoom app installed and updated to the latest version. Once you are in a Zoom meeting, the screen sharing process is straightforward but requires a few preparatory steps to ensure smooth functionality.

Begin by locating the Zoom meeting controls at the bottom of your Zoom window. The “Share Screen” button is typically a green icon with an upward arrow. Clicking this button will open a selection window where you choose what you want to share.

You can share:

  • Your entire desktop screen
  • A specific application window (such as Safari, Keynote, or a document)
  • A portion of your screen (customizable area)
  • A whiteboard for collaborative drawing
  • iPhone/iPad screen via AirPlay or USB cable connection

Before sharing, it is important to check macOS permissions, as screen sharing requires Zoom to have screen recording access. To verify this:

  • Open System Preferences on your iMac.
  • Navigate to Security & Privacy > Privacy tab.
  • Select “Screen Recording” from the sidebar.
  • Ensure Zoom is checked to allow access.
  • If changes are made, you may need to restart Zoom or your computer.

Once permissions are set, return to Zoom and select the window or screen you want to share, then click the “Share” button at the bottom right of the selection window.

Additional Sharing Options and Controls

While screen sharing, Zoom provides several tools and settings to enhance the sharing experience:

  • Pause Share: Temporarily stop sharing without ending the session.
  • Annotate: Allows you and participants to draw, highlight, or add text on the shared screen.
  • Remote Control: Grant control of your screen to another participant for collaborative work.
  • Share Computer Sound: Enable this when sharing videos or audio to ensure participants hear the sound.
  • Optimize for Video Clip: Improves video playback quality during screen sharing.

These controls appear in a floating toolbar at the top of the screen once sharing begins. You can move this toolbar around or minimize it to prevent obstruction.

Sharing Your Screen on Zoom Using an iMac

To share your screen during a Zoom meeting on an iMac, follow these detailed steps to ensure a smooth and professional presentation experience:

Before you start screen sharing, ensure your Zoom application is updated to the latest version to avoid compatibility issues. Also, verify that macOS permissions for screen recording are correctly configured, as macOS requires explicit consent for apps to capture your screen.

  • Open Zoom and join a meeting: Launch the Zoom app on your iMac and either start or join a meeting where you want to share your screen.
  • Locate the Share Screen button: At the bottom of the Zoom meeting window, find and click the green Share Screen button.
  • Choose what to share: A new window will appear displaying all available screens and application windows. You can select:
    • Your entire desktop (Screen 1, Screen 2, etc.)
    • A specific application window (e.g., Safari, PowerPoint, Preview)
    • A portion of your screen using the advanced sharing options
  • Enable sharing: After selecting the desired screen or window, click the Share button in the bottom right of the selection window.

Once sharing begins, a green border will highlight the area being shared. The Zoom toolbar will float on your screen, allowing you to pause or stop sharing at any time.

Granting Screen Recording Permissions in macOS for Zoom

MacOS requires explicit permission for applications to record your screen. If Zoom cannot share your screen, you need to enable this permission manually:

Step Action Details
1 Open System Preferences Click the Apple menu () in the top-left corner and select System Preferences.
2 Navigate to Security & Privacy Click on Security & Privacy and then select the Privacy tab.
3 Screen Recording section Scroll down the sidebar and select Screen Recording.
4 Allow Zoom Check the box next to zoom.us to allow screen recording.
5 Restart Zoom Quit Zoom completely and reopen it for changes to take effect.

Without this permission, Zoom will not be able to share your screen, and you may receive a prompt asking you to enable it during your first attempt to share.

Using Advanced Screen Sharing Options on iMac

Zoom provides several advanced sharing features to tailor your screen sharing experience on an iMac:

  • Portion of Screen: Share only a specific area of your desktop by selecting the Advanced tab and choosing Portion of Screen. Resize and move the green box to define the area.
